Problems solved by technology

Since the polyester melt is a non-Newtonian fluid and is a viscoelastic fluid, it will undergo elastic deformation and form a certain pressure while viscous flowing in the spinneret hole. Therefore, the polyester melt will flow out of the spinneret hole A certain pressure drop is generated, and the shape, size, length and relationship between the spinneret holes will have a great impact on the pressure drop. Existing research generally only considers the same shape or cross-sectional area of ​​the spinneret holes are equal, but the influence of shape, size and length is not involved, which will cause the pressure drop of the polyester melt to flow out from the different shapes of the spinneret holes of the same spinneret, so that the fibers with different cross-sections There is a difference in the extrusion speed between them, which affects the smooth progress of the fiber spinning process

Abstract

The invention relates to a moisture absorption and perspiration fiber and a preparation method thereof. The moisture absorption and perspiration fiber is prepared by measuring polyester melt, extruding by a compositing spinneret plate, cooling, oiling, stretching, thermally shaping and coiling, wherein the composite spinneret plate is provided with a cross spinneret hole and a spinneret hole shaped like the Chinese character Wang, a length ratio of micropores of the cross spinneret hole and the spinneret hole shaped like the Chinese character Wang is equal to a product of an equivalent diameter ratio of the cross spinneret hole and the spinneret hole shaped like the Chinese character Wang and a coefficient K, the equivalent diameter is a ratio of an area and perimeter of a cross section ofthe spinneret hole, the valuing range of the coefficient K is 0.97 to 1.03, an oiling agent comprises crown ether, the content of the crown ether is 67.30 to 85.58 percent, and a capillary parameterof the prepared moisture absorption and perspiration fiber is greater than or equal to 0.16. The preparation method is simple and reasonable in method, and the prepared fiber has excellent moisture absorption and perspiration performance and has good popularization value.
